LOW-DIMENSIONAL STRUCTURES: SPARSE CODING FOR NEURONAL ACTIVITY [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2013
Neuronal ensemble activity codes working memory. In this work, we developed a neuronal ensemble sparse coding method, which can effectively reduce the dimension of the neuronal activity and express neural coding.

A weighted block cooperative sparse representation algorithm based on visual saliency dictionary

open access: yesCAAI Transactions on Intelligence Technology, 2023
Unconstrained face images are interfered by many factors such as illumination, posture, expression, occlusion, age, accessories and so on, resulting in the randomness of the noise pollution implied in the original samples.
